SUMMARY

Objects in space, particularly those located far from gravitational fields, do not move at extremely high speeds due to the principles of Newton's First Law of Motion. While these objects experience minimal forces, their mass inherently resists changes in motion, maintaining their existing velocities. The discussion highlights that bodies in the universe typically move at high speeds due to significant gravitational influences, but those far from such influences retain the velocities they had when departing from stronger gravitational fields.

PREREQUISITES
  • Understanding of Newton's Laws of Motion
  • Familiarity with gravitational forces in astrophysics
  • Basic knowledge of mass and inertia
  • Concept of velocity in a vacuum
NEXT STEPS
  • Research the effects of gravitational fields on object motion in space
  • Study Newton's Laws of Motion in detail
  • Explore the concept of inertia and its implications in astrophysics
  • Investigate the velocities of celestial bodies in different gravitational environments
USEFUL FOR

Astronomers, astrophysicists, students of physics, and anyone interested in the dynamics of motion in space.

I wanted know how objects move through space, say in between galaxies furtherest from a gravitational field. I was wondering why is it that they don't move at extremely high speeds. If these objects have almost no forces acting of them or more importantly no means of resistance, then what prevents them from moving at high speeds. Will mass resist motion even in this situation?
 
Astronomy news on Phys.org
Newton's 1st law applies. Without an external force, an object will keep moving in a straight line at whatever speed it happens to have. Mass resists changes in motion.
 
Generally , bodies in Universe do move at high speeds given the great gravitational influences they are surrounded by. Bodies far from Gravitational influences will experiences minute forces which wont accelerate them much , so they continue with the velocities they had when they must have left some strong Gravitational influence.
